The respiratory system is made up of many different types of tissues and they differ according to their locations in the respiratory system.
1.Simple squamous epithelium: It is found within the alveoles of the lungs. These cells are single layer,flat (squamous) cells. It controls the permeability of blood vessels in the lungs. When you inhale it allows more oxygen to be absorbed in the blood flows.

Some modifications in the genes directly affect the protein to be synthesized, resulting in the appearance of an unexpected characteristic. It is worth noting that mutations in DNA can cause everything from physical changes to behavioral changes. This way, he has to focus on the DNA of the cell.
